There is also a margin mv"Y betweentheline of Stitching n and the adient folded edges@ l Y in the outer facing strip.; Figure 1 is la view ofa sewing,.machine l fsa, margin f In Figure 10, it will Vbe notedthatthese l margins m and m are relative'lysinall while" in Figure 11, the' margins areV relatively large, The position of the needles is indii cated in" these igiiresby` the .lines of stitch.V

a A n n l Fig; 3 is av sectional view on the lineV 3-3 ing a and n. Facing strips or plaits are usually stitched to a shirt front on a machine provided with two needles, which needles are widely spaced so as to simultaneously form the line of stitching n and a,joining the facing strips and joining the facing strips to the body fabric. These needles in machines adapted for this purpose some times vary slightly in the distance which they are set apart.

The present invention is directed to a folder which is particularly adapted for folding and directing the outer facing strip, which folder is formed so that it may be adjusted to properly direct'the strip to the needles with the spacing between the needles as found in the machine to which the folder is attached. The folder is also capable of adjustment so that the margin between the lines of stitching and the respective adjacent folded edges in the facing strip may be varied, as above noted.

Referring more in detail to the drawings, I have shown my improved folder applied to a sewing machinehaving a work support Y 1 on which thefabric is held by means of a freely on the supporting stud 12.

of stitching are formed.

presser foot 2. The fabric is fed across the iwork support by a feed dog .The stitching mechanism vincludes two spaced needles 4 and 5. These needles are carried by a needle bar 6. Cooperating with each needle is a looper 7 so that the two independent lines These parts are all of the usual construction and will not need any further description. tmay be noted that in this connection, the needles 4 and 5 are carried by a needle head at the lower end of the needle bar 6' and that the distance between these Vneedles 4 Vand 5 may vary slightly in different machines.

Attached to the work-support is a guide 8 for the under facing strip f. This guide is similar to that shown in the patent to De Nike, 7 90.560, granted May 23rd, 1905, and forms no part ofthe present invention, eXT cept as it is used to direct the under facing` strip so that it may be simultaneously stitched with the outer facing strip. The edges of this under facing strip are usually well within the marginal edges of the outer facing strip. i A

My invention is directed particularly to thel folder for directing and folding the outer facing strip or plait and the folder is indicated at 9 in the drawings. Said folder is mounted on a shank 10 which is carried by an arm 11. The arm 11 is mounted to turn The lsupporting stud 12 is rigidly carried by a bracket 13 which isv secured to the head of the machine by suitable screws passing through openings 14 in said bracket. A collar 15 is adjustably fiXed to the stud 12 and has a stop arm 16 against which the arm 11 rests when the folder 1s 1n operative relaltions 9L and 9".

stud 12 and a screw 19 operates to cause the arm to frictionally grip the stud.

The folder 9 proper, is formed of two Ysec- The section 9a is fixed to the shank 10 by suitable screws 20 and 21. This shank extends underneath both of the sections of the folder. The section 9b is also fixed to the shank by screws 22 and 23. The shank is formed with slots 24 and 25 which are adapted t0 receive respectively the screws 22 and 23. These slots extend in y. lines at right angles to the center line of the folder so that the section 9b may be adjusted later ally or in a direction at ri ht angles to the center line through the folder, by loosening the screws 22 and 23 and moving the section on the. supporting shank. Y

The section 9a has a lower guiding plate 26 and an upper overhanging guiding vplate 27. The two plates are formed integral Aat their side edges and are gradually bent yfrom a point adjacent the receiving end of the folder toward the-delivery end of the folder so as to fold underneath the edge of the strip guided thereby. end of the folder there is an inner guiding At the deliveryV` section 28 which is formed as a part of the plate26 f and the guiding recess extending about this section 28 folds the side edge of the facing strip or plait underneath the same,`

as clearly shown in Figures 3 and 4 of the drawing. The section ,9b isformed with an under guiding plate 29 and anupper overhanging plate 30. These plates are integral at their side edgesV and are shaped similarlyl to the plates 26 and 27, so as to fold' underguiding At the delivery end there is screws 33 and 34. It is also rigidly secured to the section 9b by screws 35 and 36. The

screws 35 and 36V pass through elongated slots 37 parallel to the slots 24 and 25. The" plate 26 atthe receiving end is extended at 38 so as to overlap the plate 29. Said overllapped section 38 is formed with a slot-39 through which a. screw Y40 extends. ByV

loosening the screws 22, 23, 35, 36 and 4() the whole section 9* may be moved bodily away from thesection 9a. The plate 30 khas an arm 30a which extends over the plate 27 at thereceivingendthereof. This arm 30a overlies the space between the plates and prevents the material from bending, buckling or working up between the plates.

At the delivery end of the folder, the plate 27V has an extension b=which-overliesjthe plate 30 and likewise prevents the material at the delivery end of 'thefolder from buckling, or

bending or working up between the'plates. The plates 274 and 30 atthe' receiving end of the folder are set back from the ends of the plates 26 and 29. The plates 26 and29 areformed with upturned sections Lw-bleh are adapted to guideth'eside `edges'jof the facing strip as it passes intothefolder, said facing strip being received flat and unfolded. As it passes along the folder the side edges of the facing strip or plait will be gradually turned underneath, as clearly shown in Fig. 3 of the drawings and as this facing strip leaves the folder its side edges will be folded and they will be guided by the folder to the needles. rlhe arm 11 may be adjusted endwise of the stud l2 by shifting the collars l5 and 17 carrying the stop arms. This permits thevsetting of the folder so as to obtain the desired margin m between the line of stitching n" and the adjacent folded edge-of the facing strip. The

section 9? of the folder is then set in the manner above described so as to obtain` the proper margin m between the line of 'stitching a and the adjacent folded edge 1n the facing strip or plait. In other words, by this adjustment of the folderthese two margins fm and m may be made alike and may be varied within certain limits, as desired.

It sometimes happens that the facing Y strips' vary slightly in width and my im-Y proved 'folder may be-"readily adjustedy so as to accommodate strips of different widths by the adjustments above described.

The' essential features of my improved folder consist in the bodily adjustment ofl one section of the folder relative to the other and the shifting of the folder relative to the needles so as to secure the functions above described. i

Itis obvious that-minor changes in the details of construction maybe made without departing from the spirit of the invention as set forth in the'appended'claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

l. A sewing machine including in combination, spaced needles, a folder for directing afacing strip to said'needles, a bracket,
